Product Description:
Fumed silica is widely used as a thickening agent in adhesives, sealants, and coatings to improve viscosity and prevent sagging. In the construction industry, it enhances the mechanical properties of cement and concrete, improving durability and reducing cracking. It is also a key component in silicone rubber, providing reinforcement and improving tensile strength. In paints and coatings, it acts as an anti-settling agent, ensuring uniform pigment dispersion. Additionally, fumed silica is utilized in pharmaceuticals as a flow aid in powdered formulations and as a stabilizer in liquid suspensions. Its high surface area and porosity make it effective in desiccants and as a filler in composites for improved performance.
